  • Lithium dendrite growth in solid-state electrolytes is a significant challenge for next-generation battery development. Here, authors used dark-field X-ray microscopy to investigate dislocations near dendrite tips, suggesting that stress-induced dislocation may influence dendrite branching and material fracture.

  • Strain can modify properties, but to prevent cracking is limited to films below a critical thickness. Here, by inserting atomic layers into a ferroelectric superlattice, chemical pressure is generated in thicker films, with enhanced figure of merit for tuneable millimetre-wave dielectrics.

  • Electric fields typically break symmetry when applied as a stimulus to materials. Here, by forming a superlattice of BiFeO3 and TbScO3, it is shown that an electric field can repeatedly stabilize mixed-phase polar and antipolar BiFeO3.
